. Ok, you opened the can. I'm gonna kick it over, hehe. Bare primer will not
stop rust. Primer is to give the paint something to stick to. The paint is
there to prevent rust and give it a nice look. Primer will slow down the rust
if its not painted, its a lot better than nothing. I wouldn't want to leave a
primed part unpainted too long, because primer is porous. Being porous, it will
invite crud in the air to be absorbed, including oil from your air lines and
air tools that you sand with along with moisture.  There are 3 things required
for rust to happen: water or water vapor, oxygen and ferrous metal. Remove one
of the 3 and NO RUST will ever happen. I don't understand the reason for
letting rust start and them stopping it.
A friend of mine that is now back in Peoria Ill. has a 73 Ford Mustang. Nice
car for a Ford, but he drives it on those salty roads every winter. He
prevented nearly all the rust by having a sprinkler on the driveway and he
turns on the water and drives over it.
